Had the reflash done, and then 10 miles later "catalyst is full, see manual" Back to the shop on the fifth, I wonder what caused that mess.

I got mine sitting in my shop getting ready for a 2500 mile trip. I sure hate this feeling of wondering if I am going to have problems on my trip with this 50k truck I just bought... .....

I had 2 codes in the PCM when the dealer checked it. 1 was fixed by the re-flash and the other they had to call back to Detoit to check on. It ended up needing a new catalytic converter and rear temperautre sensor and there are 270 converters on backorder (probably from the Denver warehouse) so it's anybody's guess when I'll get the truck back. I've had the truck for about 3 weeks and almost half of that it's been in the shop.

I have one quick question how can you tell when the regening is happening. I have just under 6000 miles on my 6. 7 and don't know if its done it 1 time or 5000 times. Thanks

TSB Revised to 18-033-07 REV. B

Just had my bulletin done today... ... . 10:00 am appointment, but they were already involved with a dealer in-stock unit when I got there.



18-033-07 REV. B was issued 06/28/07 and supersedes REV. A. I guess procrastination paid off in the form of one less trip to the dealer... ... . for now anyway. :-laf



Took around 35 mins to complete... ..... and some additional time because the dealer was experiencing some internet difficulty.



I was down to 4 gals remaining, so I re-fueled within 1/2 mile of the dealership. I'll have a fresh tank of fuel to make some comparisons in regards to fuel economy. Tank #1 was 14. 591; Tank #2 was 14. 457; Tank #3 was 15. 051..... all hand calculated. Hopefully the fuel economy won't nose-dive ! :-laf

Hi J. ,



I think your decision to try elsewhere is a good one.



My truck was built in Mexico. The TSB/re-flash was accomplished by my dealer (Dishman) at the dealership. (The TSB makes no exceptions for Mexican-built trucks. )



Everything points to your service tech being mistaken. It is unfortunate that he is finding it difficult to accept the new info. We TDR members are all very lucky to have a nation-wide cross-check system of fellow-owners and their service departments, so we are not limited-to/at-the-mercy-of any one individual or dealer, who may not be fully up to speed on one issue or another.



Good luck with the new service dept, ... and your rig.

Hey Wolfy,



Took my rig to Fremont Motor Company here in Cody. I was highly impressed with the level of service I received from this dealer. They applied four updates including 18-033-07 Rev B. The other was for a rough shifting issue and the thermometer was not working correctly. They are sending me the list of updates and the TSB's in the mail. I am glad I took my truck to these guys.

Great news!



Gotta be a good feelin' to have your truck in the hands of guys you think you can trust with it.

The exact same thing happened to me. Had the update yesterday and the "catalyst is full, see manual" message today. Took it back to the dealership and they provided me with the dealerconnect technical document which states it is now my responsibility to drive at 50/60 miles per hour for 45 minutes to clear the soot. That will be impossible here to drive continuously for that time at that speed. Makes me very unhappy to say the least. I wonder what percentage of their market drives their vehicles like that.

Hi Rowdy,



"Passive" regeneration happens as a matter-of-course, while driving at normal highway speeds/exhaust temperatures, ... you will not realize it, ... it is described by Cummins as being "transparent" to the driver.



"Active" regeneration can apparently be noticed as an unusual and sudden increase in exhaust gas temperature, if you have an EGT sensor/gauge to show it.



Reports vary as to frequency of this event,... with fuel and driving habits seemingly the most common variables.



My own truck, for instance, did not exhibit this indication untill it had around 1000 miles on the odometer. At speeds which usually maintained about 900-1000 degrees on the gauge, the temp went to 1200-1225, and stayed there, interrupted when I slowed/stopped, and returning when I resumed a steady speed for awile.



I got home after maybe 15 min of this, and have not driven since, so don't know if the process will resume-till-finished as described by Cummins, or not.



I assume the ECM is recording the time spent in "active" regen.



This has beeen my first/only experience of this, so have little to go on,... except for the reports of other TDR members.



An EGT gauge is highly reccomended, if you don't have one.



Good luck,

My daily drive to work and back is only 18 miles one way and never more than 10 minutes at 50/60 mph before slowing or stopping and I have yet to have an issue with regeneration.



Go here for some interesting reading on the Cummins 6. 7 including the DPF and regeneration... I think you can view it without registering.

Thanks wolfy. I have been looking into guages. These new pickups have alot of info and I would see some of that.

Tsb -07-021

Any one have an idea of what this is about or where I can find out? Dealer did this to my truck yesterday and said it was part of the reflash for the re jen what do you think?
